Hydraulic hanger of double block type sleeper for passenger special line

Abstract

The invention relates to a hydraulic hanger of a double block type sleeper for a passenger special line, belonging to double block type sleeper product pile and loading devices and comprising a small-sized hydraulic station, lifting eyes, a fixed hanger frame, an execution oil cylinder, a movable telescopic link, movable telescopic integrated suspension arms, a buffer positioning protective rod and movable arm lifting support plates; the movable telescopic integrated suspension arms capable of stretching and retracting are respectively arranged at two ends of the fixed hanger frame so as to form a door type structure, i.e. two movable telescopic integrated suspension arms are respectively connected with two ends of the fixed hanger frame through the execution oil cylinder and the movable telescopic rod which are fixedly arranged on the fixed hanger frame; the fixed hanger frame is symmetrically provided with the lifting eyes; the hydraulic station is arranged on the fixed hanger frame; the buffer positioning protective rod is arranged below the fixed hanger frame; evenly-distributed movable arm lifting support plates are longitudinally arranged inside the movable telescopic integrated suspension arms; and opposite movable arm lifting support plates are positioned on the same plane. The hydraulic hanger has the advantages of flexible operation, orderly piling, safety and reliability, improves the operation efficiency, reduces the labor intensity and ensures the quality of products.

Problems solved by technology

[0002] With the rapid development of high-speed railways in my country, high-speed railway concrete double-block sleepers are used for the laying of high-speed railway ballastless track subgrades, and are used to carry various driving forces under the rails. In the prior art, forklifts are generally used for stacking and loading. Car operation, low operating efficiency, the product is easily deformed by force due to improper operation of the forklift, and the product is deformed due to external force and the product is scrapped, so it has an impact on product quality; limited by the conditions of the forklift itself, it cannot be stacked neatly like using a spreader. Loading The last sleeper is not suitable for long-distance long-distance transportation

At the same time, the forklift itself has high fuel consumption and high maintenance costs, which is not conducive to environmental protection

High-speed railways have very high requirements on the accuracy of the subgrade under the rails. The advantages of using double-block sleepers are less investment, cost-saving, easy production, relatively easy construction methods, easy quality control, and low maintenance costs; the disadvantage is that double-block sleepers use steel trusses The relative rigidity is relatively poor, the truss is easily deformed by force, and the sleeper is easily deformed, which directly affects the accuracy of roadbed laying, thus affecting the stability of locomotive running at high speed

Especially in the process of stacking, loading and unloading, and transportation, the products are easily deformed by force, stacking and loading operations are very frequent, the span of the gantry crane is large, the area of ​​the finished product warehouse is large, the number of layers of sleepers is high, and the operation is not safe for personnel
